General questions *are still totally clueless when it comes to the topic of car*

Servus I will soon make my driver’s license for driving with an accompanying person and inform myself now already, what kind of cars I can then buy at my 18. I have a budget of 4000-450€ where 450€ is really the limit there is not even 10€. Now I have a few questions because I really don’t know well at all. 1. My father I think I can buy a car with a maximum of 100 HP, otherwise is that a completely different class and I pay with the insurance juicy dra uf. Bzw more than 1000€. Is that true? How much is normal as a beginner? 2. I actually find older cars a lot better than the new ones. I.e. Toyota Supra has always been my dream car but that has become so rare that I certainly can’t afford it in good condition. So : Do you know your car with the criteria? : 1.Sports design a lâ Toyota Supra , Mitsubishi Eclipse , Nissan Skyline, Nissan Silvia. 2. No more horsepower than 100…. maximum limit 110 HP 3. Should e be affordable and around 4000 in reasonably good condition. May be that this has ended up in the wrong topic but I have no idea where else to put it in. THX
